I run a win 2k8 a/d server and an win 2k8 exchange 07 server

I have a group called 'No Internet Mail', i made it a distribution group.

I tried to setup a transport rule on the exchange server that is configured as follows for outgoing:

from a member of no internet mail

   and sent to users outside the organization

redirect the message to administrator

   and send message refused, forwarded to administrator. Please talk to management for external email use.

however , when i enable this it forwards everyones emails to me regardless if they are a member of the no internet mail group or not.

not sure what im doing wrong, thanks in advanced.
